This problem was mainly my own doing.  Earlier today I had made a
change to the allow-transfer clause on the master while trying to
track down another issue and I forgot about it.  Allow-transfer
should, in almost all cases, be set to 'any;'.

I still have some named issues that have me puzzled but, no doubt,
these will eventually yield to further investigation.  One source of
problems is that some of the servers are CentOS-4.8 running Bind
9.2.4 while others are centOS-5.4 running Bind 9.3.6 and there are
differences in how the named.conf file is parsed.
